current room temperature with arduino

It is simple basic arduino project

you need

Arduino Uno

Dht 11 temperature & humidity sensor

data cable & jumper wire

 Please watch this video

connection diagram

arduino code

#include <dht.h>

dht DHT;

#define DHT11_PIN 7

void setup(){

  Serial.begin(9600);

}

void loop()

{

  int chk = DHT.read11(DHT11_PIN);

  Serial.print("Temperature = ");

  Serial.println(DHT.temperature);

  Serial.print("Humidity = ");

  Serial.println(DHT.humidity);

  delay(1000);

}
